Cloud Messaging extension (push notifications)

One of the targets of the Simple Terminal Client is mobile devices such as mobile phones. This kind of devices have very strong requirements for power saving (Power Management for Mobile Devices). To make access for these devices more comfortable we added support of a native activation mechanism to Simple Terminal Client. Now we can activate devices via Google's Firebase Cloud Messaging which is a native mechanism for Android devices.

Managing connection state

To do this, the BrandMeister DMR Server supports the following new messages that may be sent by the client:

TBD

Switch connection state to idle. In the idle state the server stops sending any messages to the client via UDP (keep-alive messages are not required).

Downstream message

In the connection's idle state the server will send any data such as the headers of any voice calls, data calls, and CSBK (but not voice frames) via Cloud Messaging. Client applications should then go back and switch the connection to an active state to get a stream over UDP.

Application IDs and keys

We strongly recommended to use your own application token ID. In that case please provide us your application token ID and authorisation key. Both will be hardcoded in the source code. Default application token ID is 393838907279
